This is my java code. package com; import net.jxta.impl.id.UUID.PeerGroupID; public class Test { public static void main(String args[]) { System.out.println("This is a test program."); System.out.println("TEST ID:"+PeerGroupID.defaultNetPeerGroupID.toString()); } } In the java console I am getting output from the first line. But it is giving exception at the second line. The program is running successfully from the command prompt. It seems that it is not loading jxta.jar please help. sitansu
